Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for fixing a joint site such as a bone.
[0002]
[Prior art]
When a leg bone, a finger bone, a skull, or the like is broken, it is necessary to fix the joint site for a certain period in a reduced state.
[0003]
Conventionally, in the case of a foot bone or a finger bone, a joint portion is fixed with a bolt or a plate made of metal or the like, and in the case of a skull, it is fixed with a stapler stud.
[0004]
[Problems to be solved by the invention]
However, when fixing with a bolt, a plate, or a stapler, it is necessary to pierce the bone, and damage to the bone is not desirable because there are problems such as infections. In particular, the bones of young children during the growing season should be avoided as much as possible.
[0005]
Further, as described above, it is necessary to pierce the bone, and after the piercing, it is necessary to perform an operation of fixing with a bolt, a plate, or the like, so that the operation requires considerable labor and time. In addition, it takes a considerable amount of time and effort to remove from the bone after joining is completed.
[0006]
The present invention has been made in view of the above points, and can fix a bone easily and in a short time without damaging the bone. An object of the present invention is to provide a method for fixing a joint portion such as a bone, which can easily and quickly perform this.
[0007]
[Means for Solving the Problems]
Thus, the gist of the present invention is characterized in that an instant adhesive mixed with hydroxyapatite powder is applied around a joint site in a reduced state such as a bone, and is hardened and fixed. To fix a joint such as a bone.
[0008]
In the above method, the instant adhesive used therein is preferably a photocurable instant adhesive.
[0009]
In addition, the gist of the present invention is to apply an instant adhesive mixed with a hydroxyapatite powder to the periphery of a joint site in a reduced state of bone or the like, and to irradiate light and cure in a short time. is there.
[0010]
The instant adhesive used in the method is preferably a photocurable instant adhesive.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a cross-sectional view showing a state where an instant adhesive is applied around a joint portion of a bone.
[0012]
In the figure, 1 is a leg bone, and 1a and 1b are fracture sites. Then, the fracture sites 1a and 1b abut the end faces of the bones and fill the missing portions with appropriate artificial bone material to reduce the fractures.
[0013]
In this state, the instant adhesive 2 mixed with hydroxyapatite powder is applied around the fracture site, that is, around the joint sites 1a and 1b, and fixed by hardening.
[0014]
In addition, the hydroxyapatite powder (molecular formula: Ca10 (PO4) 6 (OH) 2) has been proved to have excellent bone cell inducing ability and bone affinity, and is adapted to a fracture site to assist in bonding thereof. I do. Further, as the instant adhesive 2, in this embodiment, an α-cyanoacrylate instant adhesive having a photocuring function is used. In this case, after the photocurable instant adhesive is applied, it is instantaneously cured by, for example, irradiating a halogen light. Then, the instant adhesive 2, which is applied around the joint portions 1a and 1b of the bone 1 and hardened to form a tape, is left as it is until it is completely joined. It is to be removed. Also, in this case, if a part is cut using a blade or the like and then peeled off, it can be easily removed.
[0015]
【The invention's effect】
According to the present invention, it is not necessary to pierce as in the prior art, so that the fixing operation can be completed simply and in a short time without damaging the bone. In addition, when the bone is removed from the bone after the joining is completed, this can be easily and quickly performed. In addition, since the fixing operation and the removing operation can be performed in a short time as described above, the possibility of being infected with various infectious diseases during the operation can be significantly reduced as compared with the related art.
